Instant Pot 15 Bean Soup With Sausage. It's time for a hearty soup with ALL THE BEANS, with sausage and Cajun flavors, ready in under an hour, thanks to pressure cooking.



Dry Beans - Soak

  • 20-ounce bag 15 bean soup mix (dry beans)
  • 8 cups water for soaking
  • 2 teaspoons fine sea salt for soaking

Instant Pot 15 Bean Soup With Sausage

  • 1 tablespoon olive oil
  • 1 pound andouille sausage, cut into ½-inch rounds (or smoked sausage or kielbasa)
  • 1 medium onion, diced
  • 1 rib celery, diced
  • 1 red bell pepper, diced
  • 2 cloves garlic, minced
  • ½ teaspoon fine sea salt
  • 2 tablespoons cajun seasoning
  • ½ teaspoon cayenne pepper
  • 4 cups chicken broth (homemade chicken broth or store-bought low sodium)
  • 1 teaspoon fine sea salt (if using homemade broth)
  • 2 cups water (or more chicken broth)
  • 15-ounce can diced tomatoes with green chilies
  • 1 teaspoon fine sea salt
  • 1 teaspoon fresh ground black pepper


  1. Sort, rinse, and soak the bean mix: Sort the beans, discarding any stones, dirt, or broken beans. Rinse the beans, then do an overnight or a quick soak.
  2. Overnight soak: Cover the beans with 8 cups of water, and sprinkle with 2 teaspoons of salt. Leave the beans to soak for at least 8 hours or overnight. Drain the beans and discard the soaking liquid.
  3. OR: Pressure Quick Soak for 1 minute with a 30-minute rest: Put the beans and 8 cups of water in an Instant Pot or another pressure cooker. Sprinkle with 2 teaspoons of salt. Pressure cook at high pressure for 1 minute (use Manual, Pressure Cook, or Pressure Cook - Custom mode in an Instant Pot). Let the beans soak in the pot for 30 minutes, then quick release any remaining pressure. Drain the beans and discard the soaking liquid.
  4. Brown the sausage: Heat the olive oil in an Instant Pot set to Sauté Mode - High (use medium-high heat in a stovetop PC) until the oil starts shimmering. Add the andouille sausage and cook, occasionally stirring, until browned around the edges, about 3 minutes. Scoop the sausage out with a slotted spoon and move it to a bowl.
  5. Saute the aromatics and spices: Add the onion, celery, bell pepper, and garlic to the pot, and sprinkle with ½ teaspoon salt. Sauté, stirring often, until the onions soften, about 5 minutes. Stir in the Cajun seasoning and cayenne pepper, and sauté for 1 minute to toast the spices.
  6. Everything in the pot: Pour the soaked beans into the pressure cooker, and add the browned sausage. Stir in the chicken broth (and 1 teaspoon of salt if using homemade broth), water, and diced tomatoes with chilies.
  7. Pressure cook the bean mix for 15 minutes with a Natural Release: Lock the lid on the pressure cooker. Cook at high pressure for 15 minutes in an Instant Pot or other electric pressure cooker. (Use Manual, Pressure Cook, or Pressure Cook - Custom mode in an Instant Pot, set for 15 minutes). Or, cook for 12 minutes in a stove top PC. Let the pressure come down naturally, about 20 minutes. (If you're in a hurry, you can quick pressure release any remaining pressure after 15 minutes.) Unlock the lid, tilting it away from you to avoid the hot steam.
  8. Serve: Stir 1 teaspoon of salt and 1 teaspoon of fresh ground black pepper into the soup. Serve with hot sauce and enjoy!
